Ligne d'extrusion de tuyaux en spirale renforcée en acier

The steel reinforced spiral pipe has a high round stiffness and good flexibility in axial direction, so that the pipe system has the features of flexibility. When some unfavorable situations such as the soil subside unevenly, rise of underground water, the load of the partial ground is too big, earthquake or other disasters occurs, the pipe can be adapted to the situations by flexible deformation, so that the connection point will not leak or break due to the big stress and deformation. This pipe has combined all the advantages of the normal no pressure plastic pipes and the strength of the steel rib, so this pipe can meet different engineering requirements, this pipe can be used widely for delivery of corrosion or non-corrosion no pressure liquids.
